CONTEXT: Several recent randomised trials have evaluated the role of combination systemic treatment using androgen deprivation therapy (ADT) plus chemotherapy or an androgen receptor signaling inhibitor (ARSI) in patients with high-risk and/or unfavourable nonmetastatic prostate cancer (nmPC). OBJECTIVE: To assess the outcomes associated with adding combination systemic treatment to primary definitive local therapy in patients with high-risk and/or unfavourable nmPC. EVIDENCE ACQUISITION: We queried the PubMed, Web of Science, and Scopus databases and conference abstracts to identify prospective randomised trials examining the value of adding chemotherapy or an ARSI to ADT and primary local therapy with curative intent for nmPC. The primary endpoints were overall survival (OS), cancer-specific survival (CSS), metastasis-free survival (MFS), and failure-free survival (FFS). Secondary endpoints included adverse events (AEs) and pathologic outcomes. EVIDENCE SYNTHESIS: We identified 15 randomised studies, of which nine evaluated chemohormonal and six investigated ARSI-based treatment strategies. In both radical prostatectomy (RP) and radiation therapy (RT) settings, addition of docetaxel to ADT was associated with significantly better CSS (pooled hazard ratio [HR] 0.68, 95% confidence interval [CI] 0.49-0.95; p = 0.025), MFS (pooled HR 0.82, 95% CI 0.71-0.95; p = 0.008), and FFS (pooled HR 0.70, 95% CI 0.62-0.79; p < 0.001); the difference did not meet the conventional level of statistical significance for OS (pooled HR 0.86, 95% CI 0.73-1.01; p = 0.072). For patients treated with RT alone, docetaxel-based combination treatment did not meet the significance threshold set for OS (p = 0.3), CSS (p = 0.072), or MFS (p = 0.079), but the difference for FFS was statistically significant (pooled HR 0.72, 95% CI 0.63-0.84; p < 0.001). On network meta-analyses including RT studies, ARSI + ADT outperformed docetaxel + ADT for survival endpoints and had a more favourable AE profile. CONCLUSIONS: Intensification of systemic therapy with docetaxel or an ARSI in addition to ADT improves oncologic endpoints in high-risk and/or unfavourable nmPC treated with local definitive therapy. The highest efficacy was achieved with ARSI + ADT, specifically in patients treated with RT. PATIENT SUMMARY: Our findings highlight that selected patients with high-risk nonmetastatic prostate cancer benefit from intensification of systemic therapy beyond hormonal treatment.

Pathogenic sequence variants (PSV) in BRCA1 or BRCA2 (BRCA1/2) are associated with increased risk and severity of prostate cancer. We evaluated whether PSVs in BRCA1/2 were associated with risk of overall prostate cancer or high grade (Gleason 8+) prostate cancer using an international sample of 65 BRCA1 and 171 BRCA2 male PSV carriers with prostate cancer, and 3,388 BRCA1 and 2,880 BRCA2 male PSV carriers without prostate cancer. PSVs in the 3' region of BRCA2 (c.7914+) were significantly associated with elevated risk of prostate cancer compared with reference bin c.1001-c.7913 [HR = 1.78; 95% confidence interval (CI), 1.25-2.52; P = 0.001], as well as elevated risk of Gleason 8+ prostate cancer (HR = 3.11; 95% CI, 1.63-5.95; P = 0.001). c.756-c.1000 was also associated with elevated prostate cancer risk (HR = 2.83; 95% CI, 1.71-4.68; P = 0.00004) and elevated risk of Gleason 8+ prostate cancer (HR = 4.95; 95% CI, 2.12-11.54; P = 0.0002). No genotype-phenotype associations were detected for PSVs in BRCA1. These results demonstrate that specific BRCA2 PSVs may be associated with elevated risk of developing aggressive prostate cancer. SIGNIFICANCE: Aggressive prostate cancer risk in BRCA2 mutation carriers may vary according to the specific BRCA2 mutation inherited by the at-risk individual.

Comorbidities may increase the negative effects of specific anticancer treatments such as androgen suppression therapy (AST). OBJECTIVES: To compare 6 months of AST and radiation therapy (RT) to RT alone and to assess the interaction between level of comorbidity and all-cause mortality. DESIGN, SETTING, AND PATIENTS: At academic and community-based medical centers in Massachusetts, between December 1, 1995, and April 15, 2001, 206 men with localized but unfavorable-risk prostate cancer were randomized to receive RT alone or RT and AST combined. All-cause mortality estimates stratified by randomized treatment group and further stratified in a postrandomization analysis by the Adult Comorbidity Evaluation 27 comorbidity score were compared using a log-rank test. MAIN OUTCOME MEASURE: Time to all-cause mortality. RESULTS: As of January 15, 2007, with a median follow-up of 7.6 (range, 0.5-11.0) years, 74 deaths have occurred. A significant increase in the risk of all-cause mortality (44 vs 30 deaths; hazard ratio [HR], 1.8; 95% confidence interval [CI], 1.1-2.9; P = .01) was observed in men randomized to RT compared with RT and AST. However, the increased risk in all-cause mortality appeared to apply only to men randomized to RT with no or minimal comorbidity (31 vs 11 deaths; HR, 4.2; 95% CI, 2.1-8.5; P < .001). Among men with moderate or severe comorbidity, those randomized to RT alone vs RT and AST did not have an increased risk of all-cause mortality (13 vs 19 deaths; HR, 0.54; 95% CI, 0.27-1.10; P = .08). CONCLUSIONS: The addition of 6 months of AST to RT resulted in increased overall survival in men with localized but unfavorable-risk prostate cancer. This result may pertain only to men without moderate or severe comorbidity, but this requires further assessment in a clinical trial specifically designed to assess this interaction.
